STRIPING ATTACHMENTFOR CIRCULAR-KNITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 402,854, dated'May '7,1889.

Application filed March 21, 1887. Serial No. 231,638. (ModeL) To allwhom it may concern:

Be it known that I, JAMEs A. PARR, a citizen of the United States,residing at A1nsterdam, Montgomery county, State of New York, haveinvented certain new and useful Improvements in Striping Attachments forCircular-Knitting Machines, of which the following, in connection withthe accompanying drawings, is a full, clear, and exact specification.

This invention relates to certain new and useful improvements instriping attachments for circular-knittin g machines, and has for itsobject to effect a changing of the threads that are to be taken up bythe needles and the cutting of them in such a manner that stripes areproduced in the knit fabric,which stripes run transversely to the lengthof said fabric.

The invention consists in the construction and combination of parts anddetails, as will be fully described and set forth hereinafter, and thenpointed out in the claims.

In the accompanying drawings, Figure l is a plan view of part of acircular-knitting machine with my improved striping attachmentappliedthereto. Fig. 2 is a longitudinal sectional view of the parts shown inFig. 1. Fig. 3 is a detail view taken onthe line y y, Fig. 1. Fig.4 is aside view of the parts shown in Fig. 1, parts being broken out; and Fig.5 is a detail view taken from the inside of the needle-cylinder, a partof the needle-cylinder and of the needles being shown. Fig. 6 is anenlarged detail side view of the thread-cut ting device. Fig. 7 is across-sectional View of the same on the line 00 :0 of Fig. 6. Fig. 8 isa detail view of part of the thread-cutteroperating wheel, showingdifferent arrangements of the pins on the rib thereof.

A represents the needle-cylinder, and B the cloth-presser, which pressesthe cloth down.

into the needle-cylinder and is secured on the standard B on the base Bofthe attachment in the usual manner.

O is a stitch or loop wheel which is on the outside of theneedlecylinder, the teeth of which loop-wheel pass in between the needles, said wheel being mounted on the inclined pivot O on the end of anarm, C 011 the standard 0 which is also secured on the base B of theattachment.

D is a presser-wheel on the outside of the cylinder, which is mounted ona pivot on the end of an arm, D,which is secured on a standard on thebed or base of the machine on which the needle-cylinder revolves.

The needle-cylinder A is mounted on the shaft A and is revolved by meansof a cogwheel or any other suitable driving mechanism. (Not shown.) Allthese parts,which are of the usual well-known construction, are onlyshown to illustrate my invention.

From the base ]3 of the attachment the arms E project, on which theshaft E is fixed, and on said shaft the ratchet wheel F is mounted torevolve, which ratchet-wheel is shown in dotted lines in Fig. 2, and isunited with the pattern-wheel F, also mounted to revolve on the shaft E,and provided with a circumferential groove, F and transverse grooves'inits rim for receiving the patternchain G and the laterally-projectinglugs G of the same, the links passing into the circumferential grooveand the lugs G passing into the transverse grooves, so that when saidpattern-wheel is revolved the pattern-chain G will be carried around byit. The patternchain is endless, and its length is greater than thecircumference of. the sprocket-wheel, so that the chain hangs down belowthe sprocket-wheel, as shown in Fig. 2.

From the base 13 of the attachment an arm, 1, projects, on the top ofthe outer curved end of which a spring, I, is secured, and on the freeend of said spring a lug, I is formed, which passes into thecircumferential groove F of the pattern-wheel F, at the bottom of thesame, as shown in Fig. 2, and prevents said wheels F F from accidentallyturning in either direction on the shaft E.

From the outer side of the pattern-chain a series of lugs, I-l, project,which lugs are placed at any desired points, according to the width ofthe stripes required-that is, for each stripe or pattern of a differentkind a chain having its lugs placed different distances from each othermust be provided. Where the stripes are to be close together the lugsmust be close together, and where the stripes are to be farther apartthe lugs must be a greaterdistance from each other.

A pawl or dog, J, is pivoted on one end of an arm, J, projecting fromthe lower part of the elbow-lever J mounted to rock on a shaft, J in theframe of the machine, parallel with the shaft E and in front of andbelow the same. On the front lower end of the elbowlever J 2 the rollerJ is mounted to turn and runs on a ea1n-track,A 011 the needle-cylinderA. The dog J is provided with a weighted lower end, J which causes theupper end or point of the pawl J (shown in dotted lines in Fig. 2) toengage the teeth of the ratchet-wheel F. Every time the needle-cylinderrevolves and the cam A depresses that end of the elbow-lever J 2carrying the roller J 4 the pawl is swung up and revolves theratchet-wheel F and the pattern-wheel F, connected with the same, adistance equal to the length of one of the ratchet-teeth. The upper endof the said elbowlever J 2 is connected with devices which will bedescribed hereinafter. The wheels 1? and F are not mounted directly onthe shaft E, but on the sleeve K, surrounding the same loosely, whichsleeve extends around the entire length of the shaft E to the bearings,and on one end of said sleeve a threadcutter-operating-wheel, K, ismounted, which is provided on its rim with the annular rib K placededgewise on said rim and provided with a series of apertures, K forreceiving pins L, projecting from both sides of said rib, which pins canact 011 the beveled lugs M, held on the lower ends of screws M, passedthrough two levers, N and N, pivoted. side by side at the point M on theframe of the machine, said levers extending over the upper part of thethread-cutter-operating wheel K and over the pins on the same.

By thus forming the wheel K with a circumferential rib having'aperturesextending through it parallel with its axis, as shown in Fig. 8, thepins may be readily arranged without removing them by simply pushingthem so as to project at either side of the rib or through the rib atboth sides, in which latter instance the two levers N N will ,besimultaneously acted upon. The rear ends of the levers N N are pulleddownward by spiral or other springs M", secured to the ends of the saidlevers and to the part B of the frame of the attachment. In place ofsaid springs weights can be used.

To the front ends of the levers N and N the rods N and N are connectedat their upper ends by ball-and-socket joints, and the lower ends ofsaid rods N and N are pivoted to the levers O and 0, respectively, whichlevers are both pivoted to the blade P on the standard P on the base ofthe machine,which blade P is provided with the stop-pin P which preventsthe cutting lever or blade 0 from swinging down too far. The front endsof said levers are adjacent to the wheel O that is, beyond the wheel 0in the direction in which the cylinder revolves, as is shown in Fig. 1.

To the inner side of the lever or blade 0 the spring-strip O is secured,the front end the top edge of the fixed blade P, and on the under sideof said lever O a spring, 0, is secured, the front end of which is belowthe tongue or prong O and can be held between the said tongue or prongand the upper end of the fixed blade P.

A tongue or wire, Q, as shown in Fig. 1, curved downward at its frontend, projects from a plate, Q in front of the swinging end of the blade0 and serves to guide the cut ends of the threads and prevent them frompassing under the beards of the needles. The plate Q itself serves topress down the barbs of the needles and prevents the cut ends of thethreads from getting under the barbs or beards of the needles and beingknit into and showing through the right or face side of the fabric.

From the front end of the fixed blade P the guard Q projects laterally,and at the inner end of said guard the guard-wire projects upward fromsaid fixed blade P. The guard Q guides the successive stripingthreadsinto the cutting mechanism, and the vertical guard-wire prevents thethreads from being carried too far between the cutters.

On that end of the sleeve K opposite the one on which thethread-cutter-operating wheel K is mounted the thread.-guide-operatingwheel R is mounted,which is revolved by said sleeve, and on the rim ofsaid wheel B one or two circumferential ribs, R, are formed, which areprovided with apertures for receiving pins S, which act on beveled lugsS on the lower ends of the screws 8, passed through levers S, 5*, and S,pivoted on the frame above said wheel R, the screws and the lugs onthelower ends of the same being similar to the screws M and lugs Mpreviously described. Springs M", also connected with the part B of theframe, pull down the rear ends of the lovers S, S", and S therebypressing the beveled cam-pieces S 011 the lower ends of the screws insaid levers upon the pins S.

By forming the guide-operating wheel R with parallel circumferentialribs having aligned apertures parallel with its axis the pins may bereadily pushed into proper posision for operating the three levers S S8'', either one at a time, in any desired order, or two leverssimultaneously in certain classes of work. The screws pass through thelevers S S S, and are provided with nuts S at opposite sides of saidlevers, by means of which the screws can be raised and lowered, and thecam-pieces or beveled lugs on the lower ends of the same can be adjustedto be a greater or less distance from the bottom edges of said levers.

The pins S, projecting from opposite sides of the ribs R, must be soarranged with relation to the lugs S that at all times two of the saidlugs S will rest on the rim of the wheel. Thus, when two of the lugs Sof the screws S in the levers S, S and S rest on the rim of said wheel,the remaining lug, S must rest on a pin. The front ends of the levers S,S and S are connected by rods T (see Fig. 2) with the threethread-guides U, U and U which are pivoted in the standard U on the baseB of the attachment, the rods T being provided with ball-and-socketjoints at both ends. The threads a a a are passed through eyes 6 on anarm c, on the standard d, and then are passed through apertures in thethread-guides U U U near the pivots of the thread-guides, are passedalong the under sides of the thread-guides, and are then passed throughapertures in the swinging front ends of the said thread-guides.

On the upper end of the upwardly-projecting arm of the elbow-lever J 2the dog V is pivoted, which is adapted to engage with the ratchet-wheelWV, formed on the inner end of the thread-guide-operating wheel R 'onthe sleeve K, the said elbow-lever J being provided with a slot, J inthe upper end of its upwardly-projecting arm, in which slot the pivot JT of the dog is set in the desired position and held by anadjusting-screw, J thus permitting of adjusting the dog to have agreater or less throw. The screw J 9 extends into the rear or inner endof the slot J S and bears against the pin J so that by turning the screwthe pivot may be moved farther forward or allowed to move inward orrearward, as the case may be. A jam-nut, J prevents accidental movementof the screw J The dog or pawl V rests near its pivoted end on the pinX, projecting laterally from the lever V, pivoted on the frame of theattachment and connected at the end provided with the pin X with thespring V which pulls said end upward, thereby pressing the other end inthe direction toward the chain G.

In that end of the lever V opposite the one connected with the spring Vthe screw W is held, and on thelower end of said screw WV the beveledlug or head is secured. Nuts )V are screwed on the screw W, by means ofwhich nuts the screw can be locked in different positions on the end ofthe lever V, and thus the screw can be so adjusted that its beveled heador lug 7 is a greater or less distance below the end of the lever,'ascircumstances may require.

The lugs G of the pattern-chain G at suitable intervals are providedwith extensions g, which can act on the tooth h on the upper end of anarm, h, mounted rigidly on the rocking sh aft 72/ from which the arm w(shown in dotted lines in Fig. 4) projects, the free end of whichcarries a pawl, c, which is pressed by a spring, 2", against the toothededge of an auxiliary pattern-wheel, j, pivoted at j and provided withapertures for receiving pins 1, which project from the inner side ofsaid wheel, and on said pins a hook-pawl, m, rests,

which is provided with abeveled end part, m, said pawlbeing formed onthe end of ashaft, 0, provided at its inner end with acrank, p, fromwhich the pin r projects and extends under the dog V, pivoted on theupper end of the angle-lever J The shaft 0 is pivoted in an eye, .9, onan arm, 25, projecting from the cross-piece of the frame of theattachment.

I have shown three levers, S S S and in this case yarns or threads ofthree different colors, and thus stripes of two or three differentcolors, can be produced in the fabric, any one of which may be calledthe body, but, if desired, only two levers-for instance, S S may beused, or a greater number may be provided, according to the number ofdifferent colors to be provided. It is the same with the cutting-levers.I have shown but two levers, N and N; but if a greater number of threadsis used a greater number of levers must be provided for the cuttingdevice.

The operation is as follows: The threads a, a and a are passed throughthe loops oreyes b on the arm 0' and through the thread-guides U, U andU (See Figs. 1, 2, and 4.) The thread that is being knit-a in thedrawingsis acted upon by the stitch or loop wheel in the usual manner,and is taken up by the needles as the needlecylinder revolves in thedirection of its arrow, as is shown in Fig. 1. The guide U through whichthread a passes, is held in position to deliver the thread a to thestitch or loop wheel by one of the pins on wheel R acting upon the blockon the screw S carried by the lever S While guide U is thus heldelevated the guides U U remain depressed, as shown in Figs. 1 and 2.Wheel R remains stationary until a change of thread is to be made, pawlV being held out of engagement with ratchet WV by pin X on lever V. Asthe lever J 2 is rocked by the cam-track on the needle-cylinder andrevolves the ratchetwheel F and the'pattern-wheel F, the pattern chain Gis carried around in the direction indicated by the arrow as in Fig. 2.\Vhenever one of the beveled lugs H on the chain strikes the beveledhead WV on thelower end. of the screw which will be when the end J 4 ofthe elbow-lever J is at the limit of its downward movement, the lever Vis moved upward at its outer end, the spring V brought in tension, andthe inner end of the lever and its pin X are moved downward, thuspermitting the pawl V to descend and engage with the teeth of theratchet-wheel )V, and thererotated, the pin thereon which supports theblock of the thread-guide-operating lever S will pass from under thesame, throwing the thread-guide out of operation, and another pin willengage the block on another lever and throw the thread-guide thereofinto operative position, and so 011 successively in regular or irregularorder, as may be desired. The cutter-operatin g wheel K rotates with thethreadguide-operating wheel, and the pins on said wheel K are soarranged with relation to the pins on the thread-guide-op eratin g wheelthat when a threadguide is lowered out of its operative position, and bythe movement of said guide a thread is carried between the cutters O P,the lever N will be operated by a pin 011 wheel K, which will cause theblade 0 to descend and sever the thread. \Vhen the thread is thussevered, the end thereof lead ing from the thread-guide will be held bythe spring 0 for instance, pressing it against the prong 0 the threadformerly held by said parts being thrown by movement of its threadguideagainst the loop or stitch wheel and presented thereby to the needles.The prong and the spring 0' at this time are now hold ing the secondinoperative thread against the fixed cutter. At certain intervals on thecutter-operatin g wheel K the same pin proj ects at opposite sides ofthe rib, or two pins are placed in alignment, as shown in Fig. 8, sothat the upper cutter and the prong 0 will be simultaneously raised torelease the thread held between the spring 0' and the fixed cutter, thethen active thread being passed by movement of its thread-guide betweenthe spring 0' and the fixed cutter, the movable cutter and the prongbeing at this moment moved toward the fixed cutter, whereby said activethread will be severed and held. Two threads are always held by saidmechanism, and are released one at a time, the active thread beingsimultaneously severed and held. The prong O merely serves as a movableclamping member.

The action of the auxiliary pattern-wheel and its connected mechanismwill now be described.

Vhenever one of the laterally-projecting lugs g on the chain G strikesthe prong h on the end of the e1bow-arm h, the upper end of the said armis swung from the chain, whereby the pawl 11 is swung upward andrevolves the auxiliary pattern-wheel j in the direction of the arrow y,Fig. 4, carrying the pins Z, projecting at desired intervals from theinn er side of the said wheel j to act on the beveled end on of the pawlm, which, when thus acted upon by a pin, Z, is swung up, as is also thepin 9' on the crank 19 at the inner end of the shaft 0, on which thepawl m is formed, and when said pin 9' is swung up it passes under thepawl V and keeps the same raised, so that, even when the beveled head onthe screw XV in the lever V is acted upon by one of the lugs ll of thechain G and is raised to swing down the pin X which holds the pawl Vraised, the said pawl cannot descend to act on the ratchet-wheel \V, aspreviously stated, as it is held raised by the pin 0' on the inner endof the crank 19. The action of the lugs H of the chain on the mechanismis thus counteracted by the pin r audits operating devices. If said pinr and the devices for operating it were not provided, the action of thelugs H of the chain on the head V would cause a change of thread oryarn; but by providing the pin 0- and the devices for operating it suchchange of thread. is not effected. The lugs g on the chain G and thepins Z on the wheel j may be arranged in different positions, so as tocounteract the action of the lugs II on the chain G on thethreadchanging mechanism whenever desired. For instance, the said lugs gand pins lniay be adjusted at such intervals as to suspend the action ofthe strip ing mechanism and allow the machine to go on knitting as ifthe lug II had not acted on the lever V.
